[Q] Attempting to Recover Files on Internal Memory; New to Rooting
The phone in question is a Samsung Galaxy S3 LTE. I'm kind of a newcomer to the rooting scene, although I have been doing research on and off since two years ago when I was still on a HTC Desire (I'm now on an S3 LTE) and on the verge of rooting my phone due to the abysmal internal memory.
I would like to recover photos from my sister's S3 LTE's internal memory. The S3 LTE uses MTP, so it complicates things somewhat when I try to use something like Recuva.
Question 1: My main concern about rooting is the unrooting process. From my understanding, TriangleAway is only required if I wish to reset my counter after flashing a custom ROM. However, I am not looking to do that; all I need is root access so I can create a copy of my internal memory
onto my computer for recovering the files. Would I be right in saying that since I'm not flashing a custom ROM, there's no need for me to have to bother with TriangleAway since the counter wouldn't be increasing?
Question 2: I have obtained what I believe is a copy of the stock ROM I am currently on. However, the version doesn't match exactly, so I'm feeling kind of iffy about the prospect of flashing it onto my phone. Here's my phone's version:
Here's the closest that I can find:
I'm not sure what those mean, so I reproduced what I saw on my phone when I dialed *#1234# and on Sammobile. Would the ROM be suitable?
Question 3: I am trying my best not to write anything to my internal memory because I would like to maximize the chances of me recovering the files. Does the process of rooting write data to my internal memory?
Question 4: I chanced upon this thread about backing up IMEI and NV data
. I have no questions about that, but is there anything else that I should be looking to backup before I root and unroot? Would I be losing any form of data (such as messages, call logs, etc.) when I root? From what I understand, rooting only grants superuser access.
